Am I missing a valve stem?

[CHOO CHOO]

I just purchased some new rims for my 07 Tahoe. I bought 24" Gino 498's. I had them put the tire pressure sensors in them and was wondering if that is the reason I have two valve stems in each rim. My question is that one of the rims only has one valve stem. Three of them have a valve stem in the middle of the lip and one on the back of the lip. The odd man out has one on the back of the lip. Should I worry about this?? Any advise would be awesome.

One pic has the two valve stems, the other one only has one valve stem.

I have read that its where they fill it up with nitrogen. Yeah sounds weird I thought they filled it up with the regular valve stem.

2 valve stems WTF?? did you buy them used? The one rim might be a different model year than others. Previous owner could have cracked one and had to buy a new one and they changed the weird 2 stem thing. That's the only thing I can think of. I'm pretty sure nitrogen uses a normal valve stem.

yea. There is no conversion for nitrogen. However there are rims out there that have 2 valve stems. It can be used as a purge valve to bleed off normal air when filling with nitrogen or you can hook up a gauge while filling the other. Dosent really make sense imo

Ditto. Never heard of this before. I'd figure out how the hell to get rid of those in the middle

My set of 22 menzari has the same thing I believe the second hole in the back is for (tpms) so it won't look tacky in the middle of the rim I put my tpms in the back an a regular chrome valve stem in the middle

That's exactly what I pictured in my head but this is new to me so I do not know what to say. I can say that it is not normal.
